You don't smell so good

Lobsters shun diseased members of own species

"[Scientists] suspect the lobsters' acute sense of smell gives them advanced warning of illness."

Next time someone you know is sick, tell them: "you've got yourself some lobster B.O." and shun them. Don't forget, lobsters are the cockroaches of the ocean. They will outlive all human life. Maybe because we don't smell as much.
